Application December 30, I94'6,'Se1ial No. 719,200

This invention relates material to a supporting-structura such as a roof or side wall of a building.

:Heretofore fastening :corrugated sheets to supporting structures, it has been necessary to work from "the under side or inside 'of the strucate-re, as well as the outside, for fastening the sheet to the supporting structure. In building :constructions where the walls and roofs are of nonsiderable height, :it .is necessary to build a :scaifolding under the roof structure so that the workmen ,may have access to the under side of the sheet material, and this is also true of siding material, it being necessary to build a scaffolding on the inside as well as the outside to fasten the lcorrugated sheet to the supporting structure.

It .is, therefore, the principal object of the present invention to provide :a fastening device which may be utilized for fastening sheet material to a roof structure from the top of the structure, and siding material from the outside .nnly vof the .structure.

Other objects of the invention are to provide a device running parallel with the sheet material and having its respective ends engaging the supporting structure, having stud bolts for extending through the corrugated sheet for fastening the sheets to the supportingstructure;

to provide removable ends for the fastening device so that the devices may engage the support- ;ing structure; to provide means for clamping the ends to the supporting structme; and to projvide a device of this character which is simple, economical to manufacture and efficient in operation.

LIn accomplishing these and other objectsof the present invention, .1 have provided improved details of structure, the preferredforms of which are illustrated in the accompanying drawings,

the fasteningidevice and corrugated sheets showing the sheets attachedto the fastening device. Fig. 4 is a sectional view of a modified form of invention particularly illustrating .nails for fastening the device to a supporting structure.

Referring more .in (detail to the drawings:

:1 designates a fastener embodying the features of my invention adapted to be attached to ipurlins :2 and 3 here shown to be substantially U shaped channel members comprising a supporting structure for a roof 4 comprising corru- 1gatedsheets of material. While my invention is particularlyyadazpted for fastening a roof structure "composed of corrugated sheets, it will also :be understood that it may be used for fastening siding to building structures.

The fastening device consists of an elongated member here illustrated to be -a tube, although arod or :other structure maybe utilized. Forked members :6 and 1 are provided to be removably mounted on the respective ends of the tubular member 5 to clamp the device to the purlins. The forked members have arms-8 and 9, respectively. connected by bars 10 provided with outwardly extending members H which are weldedor otherwise suitably secured to the bars. The members )H-are adapted to engage in the open ends 12 of the tubular member -5, the outwardly extending members having openings 13 aligning with openings l5 the respective ends of the tubular .memberadapte'd to receive pins l6 and I! for se- .-c-ur-ing-the,-forked members on the tubular member 5. g The armsS of the forked members 6 and are provided with threaded openings 18 and [9 adapted to receive the threaded shanks of bolts ill-for clamping the ends to the purlins.

E be arms 8 of the forked members are provided with upwardly extending threaded studs 21 and the tubular member 5 is also provided at substantially the center thereof with an upstanding threaded stud 22, although any number of studs may be supplied as desired.

In using a device constructed as described, the forked end members are secured to the tubular member by the pins l8 and l? and the respective forks engaged over the flanges 2-4 and 25 of the purlins .2 and a, respectively, by turning the tubularimember-slantwise so that the forhedmembars are inserted over the flanges. The rods are v,p'laced at spaced distances and are adapted to fit in the-corrugationsof the sheets 4 of the roofing material" The bolts .20 are screwed into the openings lB-and 19 of the arms 9 of the forked .members 6 and TI to engage against the under 'ened to the desired place.

side of the flanges 24 and 25 of the purlins to hold the fastening device in place and prevent .slipping on the purlins.

The pins 2| of the forked members are adapted to engage in the openings 26 of the corrugated sheets and the pin 22 in the opening 21 of said sheets. Washers or the like 28. may then be applied to the threaded stud bolts and nuts 29 applied to the bolts. The nuts and washers may be covered with a waterproof material, such as putty, cement or the like 30, also as illustrated in Fig. 3.

Fig. 4 illustrates a modified form of end for the rod or tubular member which comprises an extension 3| adapted to be inserted into the ends of the tubular member and fastened by pins 32, as in the preferred form of the invention. An arm 33 is provided with openings adapted to receive nails or the like 34 for fastening the end members 3| to a wood structure (not shown). The end of the arm 33 is turned transversely to form a flange 35 to engage over the wood supporting structure.

Fig. 5 illustrates an end member having an extension 36 for engaging in the open ends of the tubular member and adapted to be secured thereon by pins 31. The end member has an arm 38 provided with an offset portion 39 having a threaded bore 40. A removable jaw 4| having teeth 42 is provided for cooperating with the arm 3-8 to provide the forked member as in the preferred form of the invention. The base portion 43 of the jaw 4| is provided with an opening through which a threaded shank 44 of a bolt 45 extends to secure the jaw 4| to the arm 38. When this form of clamping forked member is applied to the flanges of the purlins. 2 and 3 as in the preferred form of the invention, the teeth 42 will engage the under side of the flanges to prevent slippage on the purlins.

Referring to the modified form of invention shown in Fig. 6, 46 represents an elongated member adapted to be extended between the purlins 2 and 3 and has a cut-out portion as indicated at 41, forming an extension 48 having an opening 49 and an upstanding stud 5!) on each end of the member 46 which extends through the sheeting 4 for securing the sheeting to the fastening device.

'form of the invention. The respective ends of the tubular member 5| are provided with slots 53 which engage the flanges 24 and 25, respectively, of the purlins 2 and 3. In attaching these devices to the purlins the members 5| are placed at an angle so that the slots will engage over the flanges and then the tubular members 5| straight- The lower portions 54 of the slotted ends are provided with openings adapted to receive a set screw or the like 55 for securing the fasteners rigidly to the purlins.

It will be obvious from the foregoing that I have provided an improved fastening device for sheeting material adapted to be supported on a roof or siding structure which may be assembled from the top of the roof or outside of the structure without the necessity of scaffolding on the inside of such structure.
